/* 
  VIDEO-HINTERGRUND IMPLEMENTATION
  ================================
  
  Struktur:
  - #hero: Haupt-Container mit Flexbox-Layout
  - .hero-video-container: Absolute positionierter Video-Container (Fullscreen)
  - .hero-video: Video-Element mit object-fit: cover
  - .hero-video-overlay: Dunkler Gradient-Overlay für Lesbarkeit
  - .container: Content-Layer über Video (z-index: 3)
  
  Responsive Strategie:
  - Desktop (≥1024px): background-1920.mp4 (1920×1080)
  - Mobile (<1024px): background-1280.mp4 (1280×720)
  - Automatische Auswahl via HTML media-Attribut + JavaScript
  
  Performance:
  - object-fit: cover = Video füllt gesamten Bereich ohne Verzerrung
  - will-change: transform = GPU-Beschleunigung
  - IntersectionObserver pausiert Video außerhalb des Viewports
  - Fallback: Linear-Gradient Background bei Ladefehlern
  
  Layer-Hierarchie (z-index):
  1. Video-Container (z-index: 1)
  2. Dark Overlay (z-index: 2)
  3. Text & Content (z-index: 3)
